1. Can I use your protective plate for my battery?

A: There are two issues to consider if you can use this protection board:
First, how many strings of your battery is, you will buy the corresponding number of series of protection board.

2. What material is your battery made of?

We have lithium iron phosphate and 18650 two parameters of the protection board, if your battery is lithium iron phosphate single nominal 3.2V need to choose in the classification of lithium iron phosphate 3.2V, if 18650 (ternary, cobalt acid, manganese acid lithium battery) single battery nominal 3.6V (or 3.7V) please choose the classification of 18650 3.7V.2. How can I tell what my battery is made of?A: You can look at the nominal voltage of your battery, lithium iron phosphate batteries are generally 3.2V, other batteries are generally standard 3.6V or 3.7V, you can also directly ask the seller of the battery is what material battery, many buyers said my battery is 18650 or 26650 soft bag, etc., this is the shape, not the material oh! We are not able to determine your battery protection parameters based on this.

3. How many protective plates of A should I choose?

A: The number of A protection plate selected depends on the motor power of your electric vehicle or the controller current limit, such as the choice of 250W or less 15A, 500W below the selection of 20A, 800W below the selection of 30A, more than 1000W motor please contact the first Wangwang, the protection board current can not be less than the controller current limit.

4. My battery is 20AH can use this protection board?

A: The size of your battery capacity is not directly related to the size of the current with this board, the large capacity is not the battery is large, mainly to see the continuous current, that is, the larger your motor, the greater the continuous current of the protection board you choose, which is not directly related to your battery capacity.

5. How should the charger voltage be set?

Lithium battery should be charged with lithium battery charger, do not use lead-acid battery charger, lead-acid charging may have high voltage breakdown protection board MOS tube, resulting in overcharge of the protection board is not protected. 18650 Battery charger voltage: battery string *4.2V.
